Hello sir, greetings of the day.
As per your query, first of all you must find the source of leakage. If the source is your bathroom then you have to solely bear the cost. But if the leakage is due to any alternation made by the society externally, then the society shall pay for the same. You can take reference from the Bye Law No 70 providing for basis of apportioning society outgoings under various heads (i) to (xvi). It has clarified that all the repairs, that are not covered by the bye-law No. 69(a) shall be carried out by the members at their cost. The expenditure of the internal leakage due to toilet, sink etc. should be borne by concerned flat holders, with the consent of the society. And in such cases there won’t be any sharing of the expenses by both the parties. Its better you find out the source and then consult with your society authorities.
Hope this solves your query.
